The AD7582KNZ is a 4-channel 12-bit medium speed CMOS Analog-to-digital Converter (ADC) which uses the successive approximation technique to provide a conversion time of 100μs per channel. An auto-zero cycle occurs at the start of each conversion resulting in very low system offset voltages, typically less than 100μV. The device is designed for easy microprocessor interface using standard control signals, CS, RD and WR. The 4-channel multiplexer is controlled via address inputs A0 and A1. Conversion results are available in 2bytes, 8LSBs and 4MSBs over an 8-bit three state output bus. Either byte can be read first. Two converter busy flags are available to facilitate polling of the converter status. The analog input voltage range is 0 to 5V when using reference voltage of 5V. The four analog inputs are all high impedance inputs with tight channel-to-channel matching typically 0.1LSBs.
